ResumoThe spectrum simulation is a powerful instrument of great practical and pedagogical usefulness, because it helps to understand the technical and the instrumental limits of parameters in optimized measurements of magnitudes of interest in physics. Monte Carlo models, based on particle and radiation transport, provide easy and flexible tools for simulating complex geometries and materials. Particularly, MCNPX code is used to compare, manipulate, and quantify simulated and measured spectra. The purpose of this work is to use this toolset to estimate the characteristics of a collimation device, avoiding permanent and temporary damages into the diode-pin detector, during direct measurements of the Bremsstrahlung’s spectrum, which was generated from diagnosis tubes with medical purpose. The simulations were made with a maximum voltage of 150 kVp, and typical charges used in radiological protocols in the medical area. Also, differential high pulse spectra, simulated and measured with a CdTe Detector, are reported.
